Output Clipping Level (Line):	+22 dBu minimum with 100k ohm load, +20 dBu minimum with 600 ohm load
Dynamic Range:	110 dB minimum
THD + Noise:	0.05% maximum (from 60 Hz to 22 kHz @ +4 dBu output level, 22 Hz - 22 kHz filter bandwidth, gain control at 50%, phantom off)
Inputs:	Transformer-balanced, 2k ohm input impedance
Outputs (XLR):	s/n < 0507 - impedance-balanced, 120 ohm output impedance, s/n >0507 - active-balanced, 120 ohm output impedance
Outputs (Tape):	Unbalanced, tip-left, ring-right, sleeve-ground, 2.4k ohm output impedance
Power (Internal):	2 AA alkaline batteries, 6 hours life typical with +4 dBu signal into 600 ohms, no phantom power
Power (External):	5 - 18 VDC via 4-pin Hirose connector (pin-4 positive, pin-1 negative), voltages above 14 VDC cause no damage to unit, but will open an internal poly fuse. Poly fuse will reset when voltage is removed
Power LED:	Green indicates power and good battery. Red indicates power and low battery. LED turns red when approximately 1 hour of battery life remain (with phantom power off). Green with external DC power

Input Clipping Level:	-10 dBu minimum
Output Clipping Level (Tape):	+11 dBu (2.75 V RMS) minimum with 100k ohm load
Common Mode Rejection Ratio:	100 dB minimum at 80 Hz, 60 dB minimum at 10 kHz
Channel Separation:	Greater than 80 dB at 1 kHz (gain controls set to 50%)
High-Pass Filters:	80 Hz or 160 Hz (switch selectable), 6 dB per octave
Phantom Power:	48 V through 6.8k resistors or 15 V through 680 ohm resistors (switch selectable)
Limiter:	Thresholds adjustable per channel from -10 dBu to +18 dBu, 10:1 limiting ratio, 5 mS attack time, 100 mS release time, Amber/Red LED indicates limiting/clipping, Dual mono or stereo linked
